Remember when anti-smoking campaigners just wanted no smoking zones in restaurants? Or how smoking was banned on flights – for various reasons, the overriding one being “public health” – the biggest lie ever told?

Over the years, puritanical anti-smokers have insisted on the ever-increasing prohibition on where smokers can enjoy their legal habit. Culminating, of course, in the 2006/2007 nationwide smoking bans in all public places.
